cramps spasms night-time

If you have night-time leg cramps or spasms 3 or more times per week, you may be eligible to participate in a research study being conducted at Sport and Spine Rehab (SSR).

You will be compensated up to $150 for involvement in this study. 

This study is examining the effect of a foam that you apply to your legs in the evenings when you are experiencing night-time cramps or spasms.

Nocturnal or night-time cramps and spasms are involuntary and painful contractions of muscles usually involving the thigh, calf or foot muscles.  A definition of nocturnal or night-time  cramps and spasms has been proposed by American Academy of Sleep Medicine International Classification of Sleep Disorders to include the following criteria:

  • A painful sensation in the leg or foot associated with sudden, involuntary muscle hardness or tightness, indicating a strong muscle contraction.
  • The painful muscle contractions occur during the time in bed, although they may arise from either wakefulness or sleep.
  • The pain is relieved by forceful stretching of the affected muscles, thus releasing the contraction.


  • Visit SSR 3 times, for an hour each time, over 4 weeks
  • Complete questionnaires about your health during each of these visits
  • Keep a log of your night-time cramps for 4 weeks

During the first two weeks you will receive no treatment. During the second 2 weeks you will receive a dispenser from which to apply foam to your legs in the evenings.
